1. Headphone Jack
The headphone amplifier in the XDA-2 is an all-discrete audiophile quality design with
excellent noise and distortion characteristics and very low output impedance. When there
are headphones plugged into this jack, the main outputs are muted, and the Volume buttons
on the front panel (and on the remote control) adjust the headphone output level. When no
headphones are plugged in, the Volume buttons adjust the main output level. Both settings
are stored independently.
2. Mute Button
Press the Mute button once to mute the output of the XDA-2; press it again to return to the
previously selected level. Pressing the Mute button mutes both the main outputs and the
headphone outputs. Pressing Volume Up immediately cancels the mute function.
3. Volume Up and Volume Down Buttons
Pressing the Volume Up button raises the Volume; pressing the Volume Down button
lowers it. A single press moves the Volume one step, holding the button causes the Volume
to move smoothly. When there are headphones plugged into this jack, the Volume buttons
on the front panel (and on the remote control) adjust the headphone output level. When no
headphones are plugged in, the Volume buttons adjust the main output level.
Volume control is via a precision digitally controlled analog resistor ladder network, which
ensures absolute repeatability and near-perfect channel matching, even at very low
settings. Unlike digital volume controls, the XDA-2’s analog volume control doesn’t reduce
bit depth nor introduce grain or distortion at low volume settings.
